Abstract
Current treatment of chronic musculoskeletal diseases does not give sufficient results despite the implementation of novel drugs and techniques in orthopaedics and physical therapy. For instance, osteoporosis treatment is currently mainly limited to drug application, while the goal of osteoarthritis treatment is to mitigate pain symptoms through physical therapy. The main therapeutic principle in the management of osteoporosis is not only to increase bone mass, but also to improve bone and the cartilage quality, which depends on the biomechanical balance. Therefore, there is a strong demand for advanced technologies that would safely and non-invasively accelerate cartilage regeneration and improve bone density. Ten years ago, a new state-of-the-art technology - "Molecular biophysical stimulation therapy (MBST)", specifically nuclear magnetic resonance therapy, emerged on the medical technology market and until now, it has shown successful results in the conservative treatment of musculoskeletal disorders, including back pain. The aim of this review is to provide an integrated, synthesized overview of the current evidence of efficacy of MBST for managing chronic musculoskeletal disorders.

Nuclear Magnetic Resonance Treatment Accelerates the Regeneration of Dorsal Root Ganglion Neurons in vitro. Front Cell Neurosci 2022; 16:859545.

Abstract
Functional recovery from peripheral nerve injuries depends on a multitude of factors. Schwann cells (SCs) are key players in the regenerative process as they develop repair-specific functions to promote axon regrowth. However, chronically denervated SCs lose their repair phenotype, which is considered as a main reason for regeneration failure. Previous studies reported a modulatory effect of low nuclear magnetic resonance therapy (NMRT) on cell proliferation and gene expression. To provide first insight into a possible effect of NMRT on cells involved in peripheral nerve regeneration, this study investigated whether NMRT is able to influence the cellular behavior of primary SC and dorsal root ganglion (DRG) neuron cultures in vitro. The effect of NMRT on rat SCs was evaluated by comparing the morphology, purity, proliferation rate, and expression levels of (repair) SC associated genes between NMRT treated and untreated SC cultures. In addition, the influence of (1) NMRT and (2) medium obtained from NMRT treated SC cultures on rat DRG neuron regeneration was examined by analyzing neurite outgrowth and the neuronal differentiation status. Our results showed that NMRT stimulated the proliferation of SCs without changing their morphology, purity, or expression of (repair) SC associated markers. Furthermore, NMRT promoted DRG neuron regeneration shown by an increased cell survival, enhanced neurite network formation, and progressed neuronal differentiation status. Furthermore, the medium of NMRT treated SC cultures was sufficient to support DRG neuron survival and neurite outgrowth. These findings demonstrate a beneficial impact of NMRT on DRG neuron survival and neurite formation, which is primarily mediated via SC stimulation. Our data suggest that NMRT could be suitable as a non-invasive auxiliary treatment option for peripheral nerve injuries and encourage future studies that investigate the effect of NMRT in a physiological context.

Nuclear Magnetic Resonance Therapy Modulates the miRNA Profile in Human Primary OA Chondrocytes and Antagonizes Inflammation in Tc28/2a Cells. Int J Mol Sci 2021; 22:ijms22115959. [PMID: 34073090 PMCID: PMC8198628 DOI: 10.3390/ijms22115959] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Revised: 05/19/2021] [Accepted: 05/24/2021] [Indexed: 12/13/2022] Open
Abstract
Nuclear magnetic resonance therapy (NMRT) is discussed as a participant in repair processes regarding cartilage and as an influence in pain signaling. To substantiate the application of NMRT, the underlying mechanisms at the cellular level were studied. In this study microRNA (miR) was extracted from human primary healthy and osteoarthritis (OA) chondrocytes after NMR treatment and was sequenced by the Ion PI Hi-Q™ Sequencing 200 system. In addition, T/C-28a2 chondrocytes grown under hypoxic conditions were studied for IL-1β induced changes in expression on RNA and protein level. HDAC activity an NAD(+)/NADH was measured by luminescence detection. In OA chondrocytes miR-106a, miR-27a, miR-34b, miR-365a and miR-424 were downregulated. This downregulation was reversed by NMRT. miR-365a-5p is known to directly target HDAC and NF-ĸB, and a decrease in HDAC activity by NMRT was detected. NAD+/NADH was reduced by NMR treatment in OA chondrocytes. Under hypoxic conditions NMRT changed the expression profile of HIF1, HIF2, IGF2, MMP3, MMP13, and RUNX1. We conclude that NMRT changes the miR profile and modulates the HDAC and the NAD(+)/NADH signaling in human chondrocytes. These findings underline once more that NMRT counteracts IL-1β induced changes by reducing catabolic effects, thereby decreasing inflammatory mechanisms under OA by changing NF-ĸB signaling.

Abstract
The present study aimed to evaluate the characteristic influence of physical therapeutic procedures of vacuum-compression therapy (VCT) on microvascular perfusion (MiP) and macrovascular perfusion (MaP) of the lower limb in diabetic patients. A sample of nine patients with a medical history of type 2 diabetes was used for the purpose of this study. Most of the subjects' medical conditions included venous and neurological complications of the lower limb, whereas the rest of the subjects entered the treatment due to injury recovery or their phlebological disease. The PeriFlux System 5000 (Perimed, Sweden) diagnostic device was used to measure MiP. The MaP was evaluated based on the perfusion index (PI) using the Extremiter monitoring device (Embitron, Czech Republic) designed to perform VCT procedures. The study found that MiP and MaP increase as an effect of VCT procedures and at the same time PI clearly reflects the effect of the applied vacuum and compression phases, verifying the method's vital influence on peripheral perfusion disorders.

Abstract
Despite various pharmacological treatments, the problem of osteoporosis is not yet solved nor decreased. Drug's adverse event and fractures after long termed pharmacotherapy indicate a need for new treatment modalities. Nuclear magnetic resonance therapy could be a supplement to exercise and an alternative or supplement to pharmacotherapy. Number of clinical studies showed increase of BMD after nuclear magnetic resonance therapy and here presented case reports of eleven well-documented cases in which patients experienced severe trauma, having a huge hematoma around the hip but did not suffer any fracture, encourage this expectation. This case report study additionally presents case reports based on the follow-up of the incidence of fractures in a group of 450 patients (males n = 55, females n = 395) with a mean age of 68.4 years. All patients had been treated with MBST - therapeutic nuclear magnetic resonance, standard cycles of 10 days subsequently and followed during a five-year period. The data indicates that NMRT might reduce a risk of fractures in osteoporotic patients.

Nuclear magnetic resonance therapy in lumbar disc herniation with lumbar radicular syndrome: effects of the intervention on pain intensity, health-related quality of life, disease-related disability, consumption of pain medication, duration of sick leave and MRI analysis. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2014; 24:1296-308. [PMID: 25326180 DOI: 10.1007/s00586-014-3601-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/29/2014] [Revised: 09/25/2014] [Accepted: 09/26/2014] [Indexed: 12/12/2022]
Abstract
PURPOSE The objective was to assess the effects of therapeutic nuclear magnetic resonance (tNMR) as a conservative treatment for lumbar radicular syndrome (LRS) in patients with lumbar disc herniation. METHODS The prospective, randomised, double-blind, placebo-controlled trial included 94 patients, aged 20-60 years (44.79 ± 8.83), with LRS caused by lumbar disc herniation confirmed by MRI scans and with clinical signs of a radicular lesion without indication for surgical intervention. Treatment group (TG) and control group (CG) received standard non-surgical therapy. Additionally, the TG had seven sessions with the tNMR device with a magnetic flux density of 2.3 mT and a frequency of 85 kHz; the CG received 7 sham treatments. Outcome parameters were the treatment effect on pain intensity (Visual Analogue Scale-VAS), health-related quality of life (36-item Short Form Health Survey-SF-36), disease-related disability (Roland Morris Disability Questionnaire-RMDQ), pain medication intake, duration of sick leave and morphological changes assessed by MRI scan analysis. RESULTS VAS scores improved significantly in both groups (p < 0.000). Only in week 4, improvement in the TG significantly surpassed that of the CG (morning pain p = 0.011, evening pain = 0.001). In both groups, SF-36 scores reflected a significant amendment in the physical component score (p < 0.000) and a significant deterioration in the mental component score (p < 0.000). SF-36 scores did not differ significantly between groups. RMDQ showed a significant amelioration in both groups (TG and CG p < 0.000), with a tendency to a superior benefit in the TG (p = 0.083). Patients in the TG recorded significantly fewer days of sick leave in month 3 after treatment (p = 0.026). MRI scan summary scores improved significantly in both groups (L4/5 p < 0.000, L5/S1 p < 0.001) and did not differ significantly between the groups. CONCLUSIONS This trial was the first to investigate the effects of tNMR as an additional treatment of lumbar disc herniation with LRS. The application of tNMR did not meet MCID criteria. It rendered few statistically significant differences between patient groups. The overall results of this trial make a clinical implementation of tNMR in the treatment of lumbar disc herniation with LRS appear premature. Further research is needed to better understand the mode of action of tNMR on compressed neural tissue and to elucidate the issue of the cost/benefit ratio.

Abstract
OBJECTIVE The aim of this study was to test whether Er:YAG laser-etched enamel of human teeth could act as a biologically active scaffold for tissue regeneration. BACKGROUND DATA Hydroxylapatite (HA) with rough surface created by acid etching treatment has been used as a scaffold for tissue engineering. However, whether tooth HA can be a scaffold for osteoblastic cell seeding is still unclear. MATERIALS AND METHODS Enamel samples from human teeth were pretreated with an Er:YAG laser to create a rough surface. Then the surface of the laser-treated enamel was examined using a surface roughness profilometer and a scanning electron microscope. In addition, static water contact angles of the Er:YAG laser-treated enamel samples were measured using goniometry. To observe the effects of cell behavior on an Er:YAG laser-roughened enamel surface, we cultured MG63 osteoblast-like cells on the surface-modified enamel samples. Alkaline phosphatase activity, a marker of cell proliferation and differentiation, was monitored and compared with that in untreated control and acid-etched enamel samples. RESULTS Er:YAG laser treatment significantly improved the surface roughness of the enamel samples. Furthermore, MG63 osteoblast-like cells cultured on the Er:YAG laser-roughened enamel surface expressed more alkaline phosphatase activity and exhibited greater degrees of cellular differentiation than did cells that had been cultured on untreated enamel samples. CONCLUSIONS These results demonstrate that Er:YAG laser-roughened enamel promotes osteoblastic differentiation. This finding suggests that Er:YAG laser-roughened enamel surfaces can potentially serve as a scaffold for tissue engineering.

Abstract
Recently, the term tensotaxis was proposed to describe the phenomenon that tensile stress or strain affects cell migration. Even so, less attention has been paid to the effects of compressive stress on cell behavior. In this study, by using an injection-molded method combined with photoelastic technology, we developed residual stress gradient-controlled poly-L-lactide discs. After culturing NIH-3T3 fibroblasts on the stress gradient substrate, the cell distributions for high- and low-stress regions were measured and compared. Our results showed that there were significantly more cells in the low-compressive stress region relative to their high-stress analogs (p < 0.05). In addition, NIH-3T3 fibroblasts in the low-compressive stress region expressed more abundant extensive filopodia. These findings provide greater insight into the interaction between cells and substrates, and could serve as a useful reference for connective tissue development and repair.
